Older Adult Single Segment Analysis
Research Question 2: For violent person crimes, when is the victimization of a person aged 65 or older in a residential setting most likely to occur?
This example uses NIBRS data to identify the time adults over the age of 65 are the
victims of violent crimes. Prior to NIBRS, national data was not available to address this
question. NIBRS provides the opportunity to investigate this type of issue.
The data source for this research question is the 1996 NIBRS hierarchical data file. There were 1,487 agencies in nine states reporting during 1996. The file used for the analysis is an incident level aggregated flat file, created by combining multiple segments of data. (See Creating an Incident-Level Aggregate Flat File for a detailed explanation of this process.) Variables from the following segments were used: administrative, victim, offender, offense, arrest, and property. Although these six segments were used, not all variables from all segments were needed for this analysis.
Variables were then created for the most serious offense, location of offense, time of
offense, and victims over the age of 65. The method of analysis is a cross-tabulation
Table 2 shows the day and time of violent person incidents involving victims over 65. The peak days of the week are Saturday (15.9%), Thursday (15.6%) and Monday (15%). The peak time period is 6 p.m. to 11 p.m. (39.4%), which is followed closely by the time period of noon to 5 p.m. (31.6%).
